Hello!
I was recently given a spa, an Outback Savannah (Outback branded Hydro Spa 910) using a Hydro Quip CS6230. I had an electrician come out to hook up the electrical. He used a Eaton 60 Amp CH Type Spa Panel (Model #CH60SPA). When he first hooked it up, the breaker would trip immediately. After looking at the manual, I noticed he had wired it wrong so I had him come back and fix it, and everything worked great.

When the weather started to get a little bit colder, the GFCI started to trip intermittently, only when I was at work, or sometimes overnight. I could never get it to trip manually when I tried. This would happen every couple days, maybe once a day sometimes. Fast forward a month and a half and now temperatures are below freezing. The spa trips at least once a day, and now I am able to trip it manually when I turn on Pump 2, but only sometimes. Sometimes it stays on and works great. Other times, pump 2 will turn on and after about 10-30 seconds, the GFCI will trip. Sometimes I can turn it right back on, and sometimes I have to wait a few minutes. I have never been able to manually trip it with pump 1 on high. I have a suspicion that this is somehow temperature/humidity related but I'm not sure how I would test that theory. I suppose it could also be pump 2, or a wire related issue. Maybe even something on the board? A capacitor or a fuse going bad? Should I try to swap out the GFCI with a new one?

Other things to note: I put a new heater element in when I got it and that works great, I'm using a used pigtail/whip(the wire that goes from the GFCI to the hot tub encased in the thick gray flexible (conduit?)) I got this from my father that had previously used it in a hot tub installed around 10 years ago. The wire is 6 gauge (it has the two power wires, a neutral and a bare ground, and it looks like the same wire the electrician used to hook the GFCI up to my main breaker. I have opened up the spa cabinet and there is no moisture near pump 2. There is a tiny bit of water near pump 1, but I couldn't find the source, just a very small leak somewhere in that area. The control box is bone dry.

Do you have any ideas? I do have a multimeter and am tech savvy so I'd be able to test anything needed.

I randomly found this and I wanted to answer my own question here. I ended up only using pump 1 throughout the winter. This summer, I pulled pump 2 and had it professionally tested, and they found nothing wrong. I then rebuilt the wet end of the pump, and that fixed it. No more tripping. I am guessing there was small, undetectable leak on the pump 2 seal that was causing the gfci to trip. So that was the answer to my nightmare. Also.. if you are going to rebuild the wet end... replace all seals AND the impeller. I made the mistake of re-using the impeller, and it shattered a few months later.
